BACKGROUND: Cerebral Venous Sinus Thrombosis (CVST) is a rare but potentially life-threatening condition, often associated with specific risk factors. The primary treatment for CVST is anticoagulation, but some cases progress to Refractory CVST (rCVST), requiring endovascular treatment. A combination of stent retriever and catheter aspiration is emerging as a promising technique to enhance treatment effectiveness. We conducted a systematic review and meta-analysis to assess the safety and efficacy of this approach, aiming to improve recanalization success and neurological outcomes while reducing complications in rCVST patients...

We report a case of the formation of a dural arteriovenous fistula (dAVF) of the transverse-sigmoid sinus following venous sinus stenting (VSS), treated with trans-arterial embolisation and venous remodelling. An obese woman in her 30s presented with persistent daily headaches after undergoing endoscopic repair of a skull base cerebrospinal fluid leak. Angiography demonstrated a focal right transverse-sigmoid sinus stenosis, and she underwent VSS of the right transverse sinus. She developed progressive pulsatile tinnitus within 3 months, and angiography demonstrated the formation of a Borden type 1 dAVF along the stent...

Sinus venosus atrial septal defects present a wide variety of anatomical features and are frequently associated with partial anomalous pulmonary venous drainage of one or more right pulmonary veins. Surgical correction used to be the standard treatment. In recent times, transcatheter correction of superior sinus venosus atrial septal defects has come into vogue. The transcatheter closure of these defects with covered stents at a tertiary care centre in Oman between 2018 and 2023 is reported.

Hemodynamic changes in stented blood vessels play a critical role in stent-associated complications. The majority of work on the hemodynamics of stented blood vessels has focused on coronary arteries but not cerebral venous sinuses. With the emergence of endovascular electrophysiology, there is a growing interest in stenting cerebral blood vessels. We investigated the hemodynamic impact of a stent-mounted neural interface inside the cerebral venous sinus. The stent was virtually implanted into an idealized superior sagittal sinus (SSS) model...

BACKGROUND: Cerebral venous sinus thrombosis (CVST) is typically associated with a prothrombotic state of the blood, with its causative factors varying widely. Prior research has not reported the simultaneous occurrence of CVST and dural arteriovenous fistulas (DAVFs) as potentially resulting from genetic mutations. In this case report, we introduce a unique occurrence wherein a patient with a heterozygous mutation of the low-density lipoprotein receptor (LDLR) gene presented with CVST in conjunction with DAVFs...

Pulsatile tinnitus is a symptom with a potentially significant impact on the quality of life of patients.1 In some cases the pulsatile tinnitus is secondary to an arterial, arteriovenous, or a venous condition that can be treated endovascularly.2-5 One of the newly recognized entities that can cause pulsatile tinnitus is the presence of an ipsilateral aneurysmal diverticulum of the transverse sinus. The Woven EndoBridge (WEB) is an intra-aneurysmal flow disruptor for the treatment of broad-based arterial aneurysms with a high safety and effectiveness profile...

PURPOSE OF REVIEW: Idiopathic intracranial hypertension (IIH) affects predominantly overweight women of childbearing age, causing chronically-disabling headaches and visual loss. Weight loss remains the most effective management strategy, but innovative treatments and randomized control trials (RCTs) remain few. This paper will review recent IIH research. RECENT FINDINGS: Pregnancy-related complications, but not losses, are increased in IIH, while symptom severity is not affected...

Cerebral venous sinus thrombosis (CVST) is a rare cerebrovascular disease that can occur at any age and generally has a good prognosis. Polycythemia vera and nephrotic syndrome are uncommon risk factors for cerebral venous sinus thrombosis. A dilemma exists in the treatment of cerebral venous sinus thrombosis with polycythemia vera and nephrotic syndrome, as some cases are refractory to first-line therapy. Here, we report a patient with CVST who presented with a generalized seizure and was found to have bilateral frontal lobe hemorrhage and subarachnoid hemorrhage...

BACKGROUND AND OBJECTIVES: Although venous sinus stenting (VSS) improves cerebrospinal fluid reabsorption and decreases intracranial pressure in patients with idiopathic intracranial hypertension (IIH), the underlying pathophysiology of IIH is not well understood. We present a review and meta-analysis of the literature on VSS for IIH treatment, focusing on the rates of restenosis and symptom recurrence. METHODS: We performed a systematic review of PubMed and Embase databases between January 1, 2011, and December 31, 2021...

INTRODUCTION: Idiopathic intracranial hypertension (IIH) can result in headaches, pulsatile tinnitus, papilledema, and other neurological symptoms. Weight loss can alleviate some symptoms of IIH. This study aims to investigate the effect of venous sinus stenting on post-operative weight and body mass index (BMI) changes among IIH patients. The secondary objective is to investigate the relationship between post-operative weight changes and papilledema resolution. METHODS: Patients with papilledema undergoing venous sinus stenting for IIH were retrospectively reviewed from two comprehensive North American cerebrovascular centers...

BACKGROUND: Current neurointerventional procedures are expanding the use of large bore microcatheters, of up to 0.033" inner diameters, to accommodate intrasaccular flow disruptors or neck-bridging devices, including flow diverters. The use of large bore microwires may mitigate the ledge gap between wire and catheter, facilitate navigation and offer support in distal tortuous anatomy. We aim to report our early experience using the novel Aristotle (Scientia Vascular, West Valley City, UT) 18 and 24 microwires in neurovascular interventions...

Superior sagittal sinus (SSS) obstruction causes intracranial hypertension, often requiring surgical stenting. Consensus on treating brain venous sinus stenosis, another cause, is lacking. This study reports a case of SSS stenosis and intracranial hypertension treated with venous stenting, improving bilateral papilledema. A 51-year-old with a headache and visual disturbance had papilledema and visual field loss. MR venography showed SSS stenosis, leading to a neurosurgery referral. Lumbar puncture confirmed intracranial hypertension (>35 cmH2O), prompting venous stenting...

OBJECTIVE: Meningiomas invading the intracranial venous sinuses may cause intracranial venous hypertension, papilledema, and visual compromise. Sinus resection and graft reconstructions, however, add significant complexity to tumor surgery, with the potential for increased morbidity. In this study, the authors explored whether venous sinus stenting might provide an alternative means of controlling venous hypertension that would be sustainable over the long term. METHODS: The authors performed a retrospective review of all 16 patients with intracranial meningiomas who underwent stenting at their institution for venous sinus compromise...

Giant arachnoid granulations (GAGs) are minimally investigated. Here, we systematically review the available data in published reports to better understand their etiologies, nomenclature, and clinical significance. In the literature, 195 GAGs have been documented in 169 persons of varied ages (range, 0.33 to 91 years; mean, 43 ± 20 years; 54% female). Prior reports depict intrasinus (i.e., dural venous sinus, DVS) (84%), extrasinus (i.e., diploic or calvarial) (15%), and mixed (1%) GAG types that exhibit pedunculated, sessile, or vermiform morphologies...
